for the trains at these stations and the operator can monitor the train
operation from OCC (Operation Control Centre). The system shall
execute the commands according to timetable.

(f) Long Route Setting & Route Stacking: The chief controller/section
controller in OCC can set long route for one station to another station.
Provision of Route stacking shall be made to set routes of multiple trains in

available, local operation of block instrument will be done by SM at
station.
